Türkiye’de Yayılış Gösteren Sumercimeğigil Üyelerinin Belirlenmesi

Lemnoideae alt familyasına ait türleri içeren sumercimekleri, çiçekli bitkilerin en küçük grubunu oluşturmaktadır. Bu çalışmada Türkiye’nin önemli sulak alanlarının bulunduğu bölgelerde sumercimeği türlerinin yayılış alanları ve bazı ekolojik özellikleri araştırılmıştır. Sumercimeği genotiplerinin bulunduğu lokasyonların koordinatları ArcGIS programı kullanılarak haritalandırılmıştır. Sumercimeğigil üyesi 5 farklı türü temsil eden 67 genotipe ait bitki örneği belirlenmiştir. Yapılan arazi çalışmalarında L. turionifera’ya ait 3 genotip; Spirodela polyrhiza’ya ait 4 genotip; Lemna trisulca’ya ait 7 genotip; Lemna gibba’ya ait 9 genotip ve Lemna minör’e ait 44 genotip belirlenmiştir. Sumercimeği olduğu tespit edilen bölgelerin rakımları geniş bir aralıkta (1-1734 m) bulunmuştur. Model bitki olarak değerlendirilebilmeleri, biyoremediasyon çalışmalarında kullanılma potensiyelleri, içerdikleri yüksek protein içeriğinden dolayı balık ve diğer hayvanlar için besin meateryali olarak kullanılabilmeleri ve içerdikleri yüksek nişasta içeriğinden dolayı biyoyakıt olarak değerlendirilebilmeleri sumercimeklerinin önemli avantajlarındandır. Bu anlamda ülkemizde yayılış alanları tür bazında belirlenen sumercimeği üyesi bitkiler değerlendirilebilir.

Determination of the Duckweed Species in Turkey

The plants of the Lemnoideae subfamily are the smallest group of flowering plants. In this study, the distribution areas of Lemnoidea species in areas where important wetlands of Turkey and some ecological characteristics were investigated. Coordinates of locations of duckweeds genotypes are mapped with ArcGIS program. 67 genotype plant samples representing 5 different species of duckweed members were identified. Three genotypes belonging to L. turionifera in the field studies; 4 genotypes belonging to S. polyrhiza; 7 genotypes belonging to Lemna trisulca. It was determined that 9 genotypes belong to L.gibba and 44 genotypes belong to L. minor. The altitudes of the areas identified as duckweed were in a wide range (1-1734 m). Duckweeds are important advantages: (1) they can be evaluated as a model plant, potentialities of use in bioremediation studies, (2) they can be used as food for fish and other animals due to the high protein content they contain and (3) they can be evaluated as biofuels because they have high starch content. The duckweed member plants whose distribution areas are determined in Turkey can be evaluated for these purposes.
